Displaying frequency polygons in Excel (Statistics)

If I would like to compare two sets of data and display using as a frequency
polygon, can I do that in Excel. I tried using scatter charts and line chart,
but it puts the data on the Y axis, and I want it to be on the X-axis. Is
there a way to define what I want displayed on the X and Y axes incrementally
without it automatically numbering these axes automatically in Excel?

An XY (Scatter) chart type uses numerical values for both axes.

The Line chart type uses category labels on the X axis (equally spaced) and
numerical values on the Y axis.

If you use an XY (Scatter) chart type to display two data series, where each
data series has both X and Y values, you can change the individual data
being displayed on the vertical and horizontal axes using Chart | Source
Data | Series.

Hi Mike,
I actually figured this one out. I needed to have the data set up adjacent
on the spreadsheet and select all of it to get the proper ranges that I was
looking for using the scatterplot graph. I do have one other question though.
My data range is ok now, with 69.5, 89.5, 109.5, 149.5, 169.5, 189.5 on the
X-axis. I had to go into Format Axis and change the min and max to 69.5 and
189.5 and then change the major unit to 20 for them all to display as I
wanted them to. However, for some reason the first two showed as 69.5, 89.5
and then the rest rounded up to 110, 150, etc. I somehow got it back the way
I wanted it, but is there a setting to change so that it doesn't round like
that when I want to show the specific class boundaries? Let me know. Thanks.

Regarding "the first two showed as 69.5, 89.5 and then the rest rounded up
to 110, 150, etc," for an XY (Scatter) chart type, I think the same number
formating (using Format Axis | Number | Linked To Source) applies to all
value labels on the X axis, so this appearance could not happen. For the
Line chart type, the X axis uses the text format of the values on the sheet,
so different number formats would be possible. I think.
